Ubuntu removed the superseded 0.9.0-1ubuntu0.1 payload from its live
archive pool, so the shared Linux CI preparation step fails with HTTP
404 before tests start. Address Ubuntu's recorded Launchpad build so
future pool pruning does not invalidate the pinned download location.
Select upstream's 0.12.0 security release for CVE-2026-87766 instead of
Ubuntu's isolated 0.9.0 backport, whose regressions and support limits
are documented by upstream in Launchpad bug 2166359. Keep checksum
verification, direct extraction, and the existing namespace probe.
Verify build 33546835 against its published SHA256 and archive SHA512.
Its amd64 ELF requires at most GLIBC_2.38 and x86-64 baseline; its
packaging requires Linux 5.10. Ubuntu 24.04 provides glibc 2.39, Linux
6.8, and the required libcap2/libselinux1 versions. This changes only
the CI helper's pinned payload, not product sandbox configuration.
Review of #4539. A refusal pnpm view prints as JSON on stdout was read
as unknown, so no registry was ever asked after a dead one; stderr and
stdout are now read alike, and a lookup killed at its bound is a
network refusal. pnpm's own registry joins the fallback plan only once
pnpm config get registry names npm's own or a configured fallback, so
a company registry in .npmrc is never followed by a public one, and a
registry pnpm already names is asked once. The Host lays each failure
at the registry or the spec's own host, reading the host off error
lines only, and reports it as ChangeResult.failedAt; a stop that lands
between attempts is cancelled, not failed. The package publishes its
registry rule through ./registry so the dialog plans with the Host's
own function, starts from the registry the Host asks first until one
is remembered, tags that one as the default, labels pnpm's own by the
host it names, and words and offers a change of registry from the
Host's attribution. ERR_PNPM_NO_OFFLINE_META is no longer a network
failure.
The install dialog folds a registry control beside the guide: the
official registry, the mirrors the Host configured, and a typed
address, remembered in this browser and passed to the check and the
run. The installing screen names the registry the Host moved on to,
each pnpm run carries its registry, and a failed run names every
registry asked, or the host a git or tarball spec could not reach,
with a shortcut back to the registry options. The Host answers the
spec's own host and the registries it asked so the dialog can say so.
Also documents the registry plan in the package READMEs, the boot
subsystem page, the catalogs, and an Agent Note; pins the flow through
a real Host/browser e2e and refreshes the tool-schema snapshots.
* ci: trial smaller Blacksmith static and observational runners
* ci: measure the 16-vCPU control for runner sizing
* ci: use 4-vCPU static and 8-vCPU observational runners
* ci: retain 8-vCPU static runner for completion time
* ci: right-size Blacksmith runners by workload
* ci: retain static runner capacity supported by utilization
* ci: retain observational runner for peak CPU and memory demand
* ci: restore Windows build to 16 vCPU after runtime regression
* ci: trial 4-vCPU runtime packaging to reduce CPU time allocation
* ci: trial 2-vCPU Linux packaging and serial Windows tests
* ci: include Windows packaging in 2-vCPU trial
The gate spec asserts line and rule per violation instead of counts; the
open-in-app fake carriers match the relative route exactly so a re-absolutized
route cannot pass; the root and mount cases of the markdown file route share
one table; a fixture echo of its own icon URL is dropped.
